Gateway mesh stop working , error "Operation cannot be accomplished in current state"

Question

Hello everyone,

I am running several mesh networks using ChirpStack OS. Randomly, the mesh system refuses to process downlinks, and the following error appears in the logs: 'Operation cannot be accomplished in current state'. I suspect this might be an issue related to the ZeroMQ protocol.

Restarting the mqtt-forward-mesh services resolves the issue, and everything starts working normally again. While I could simply set up a cron job to restart these services every hour, I would appreciate it if anyone could suggest a more elegant and permanent solution.

chirpstack-gateway-mesh --version
chirpstack-gateway-mesh 4.1.3
chirpstack-mqtt-forwarder --version
chirpstack-mqtt-forwarder 4.5.1

Thank you in advance.
